The property has to be left to the descendants but the relief is still available if the property is then sold by the executors in the course of administration:
"The actual home doesn’t have to end up in the hands of the direct descendants. An estate could still be eligible for the additional threshold if the estate’s personal representative sells the home as part of the administration of the estate and passes the sale proceeds to the direct descendants."

That said, a direction in the will to sell the property would be stretching this and, as RMC says, probably wouldn't attract the relief.
It should be fine if the will leaves the property to the descendants either outright or as part of residue by the executors then have to sell to pay prior legacies or an equity release debt.
